No such thing as "most powerful" and there haven't been for years. Oh and the fact that they are rare just means that... well they are rare, doesn't make them any more powerful, heck the Spirit Beasts aren't even that good.

way back, yes the rare pets were more powerful than their common couterparts. These days they're just skins. But if i was to list my favourite rare would be Madexx. I just love that model, favourite non rare would be rattlebore.

I know there is not such a thing most powerful, but some Player prefer some Pets and the way they fight... I just started a Undead Hunter ( lvl 53 now ) Beastmastery... I like to collect lots of Pets... but still fight only with my ghost wolf...can't wait til I get the ability to use 2 pets in one fight...
I like Skroll too... but still have to wait to get him...

GL trying to do rank 8 brawler guild fights without a spirit beast. I'm not even sure battletron is possible without a spirit beast.

No, I can't remember if I used Spirit Bond or Exhilaration but whichever I used was enough to keep me alive. If you carefully blow up a few mines with Deterrence active the damage isn't all that unmanageable.

Yes, they are? Would you rather use a cat that gives the mastery buff for the raid?
I use the heal all the time, on other players and myself. It heals for 150k if I'm not wrong.
